The Chernobyl nuclear Power plant located in the Ukraine experienced an explosion on April 26th, 1986. It was a result in part to human error and a design flaw. This emitted more radiation than the Hiroshima bomb. About 400 times more.
The reactor burned for ten days despite sand, radiation blocking lead and neutron-absorbing boron being dropped via helicopters into the reactor.
Two workers were killed immediately from the explosion. Twenty-eight engineers and firefighters died from acute radiation syndrome in the weeks that followed. A total of 134 of 600 workers were sickened with acute radiation poisoning. The ones who died, suffered agonizing deaths. The cancer deaths of those that lived in the area was estimated at about 5000.
Authorities waited over 24 hours to evacuate the area. A 1600 square mile area was designated a no-go zone. Reports of the long term effects of Chernobyl vary. Leukemia, thyroid cancer and mental disturbances have been seen in many who worked or lived in the area. Researchers found a drastic increase in birth defects in children born near the exclusion site.
Some areas have been deemed safe for short visits while others have been declared uninhabitable for 3,000 years. Despite these warnings, some have made the choice to return to the area, to their homes. The other reactors were kept running over the years until 2000, when the plant was secured and completely shut down.
